Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Pelvic organ prolapse is a common benign condition, and surgery for pelvic organ prolapse is very common. Vaginal apical suspension is one of the most common surgeries for pelvic organ prolapse. There is very limited data on the utility of preoperative gabapentin for vaginal apical suspension surgery.
This study will recruit women scheduled to undergo vaginal apical suspension surgery (either uterosacral ligament suspension or sacrospinous ligament fixation) with or without other prolapse or anti-incontinence procedures. Participants will be randomized 1:1 to preoperative gabapentin or preoperative placebo (both patients and investigators will be blinded). Note the control group will receive preoperative acetaminophen/celecoxib/placebo and the treatment group will receive preoperative acetaminophen/celecoxib/gabapentin (preoperative acetaminophen/celecoxib are part of our current ERAS protocol). The primary outcome will be postoperative opioid use in the first 24 hours postoperatively measured in morphine milligram equivalents.
